Noun: a 2nd tense pronoun used to casually address a close friend or homie; originally derived from the colloquial pronoun usage of 'pimpin' and informed by former Chicago Bulls forward, Scottie Pippen; to call someone 'pippen' often implies that they are your sidekick (see Scottie Pippen to Michael Jordan), therefore, peepin' retains some of the demoralizing tone therein
